Russia has provided Iran with information that could help Tehran strike American warships, aircraft and other assets in the region. That's according to two officials familiar with U.S. intelligence on the matter. The officials, who were not authorized to comment publicly on the sensitive matter and spoke on the condition of anonymity, cautioned that the U.S. intelligence has not uncovered that Russia is directing Iran what to do with the information. Still, it's the first indication that Moscow has sought to get involved in the war that the U.S. and Israel launched on Iran a week ago.

Russia has condemned U.S.-Israeli strikes on Iran and urged an immediate stop to the campaign and a return to diplomacy. In a Telegram post on Saturday, Russia's Foreign Ministry called the strikes preplanned and unprovoked aggression against a U.N. member state. It said the United States and Israel used Iran's nuclear program as a cover. It claimed they are really seeking regime change. Russia warned the attacks could spark humanitarian and economic disaster. It also warned of a possible radiological catastrophe, saying strikes on safeguarded nuclear sites are unacceptable. It said Moscow is ready to help broker peace.

Ukrainian President Volodymyr Zelenskyy says that Russia has not "broken Ukrainians" nor triumphed in its war. He spoke Tuesday four years after an invasion that has severely tested the resolve of Kyiv and its allies and fueled European fears about the scale of Moscow's ambitions. In a show of support, more than a dozen senior European officials headed to the Ukrainian capital to mark the grim anniversary. The conflict has killed tens of thousands of people, upended life for millions of Ukrainians, and created instability far beyond its borders. Zelenskyy said his country has withstood the onslaught by Russia's bigger and better equipped army. He added that Russian President Vladimir Putin has "not achieved his goals."

The latest U.S.-brokered talks between envoys from Moscow and Kyiv over Russia's all-out invasion of Ukraine have ended with no sign of a breakthrough. Both sides said Wednesday the talks were "difficult," as the war's fourth anniversary approaches next week. The negotiations in Switzerland were the third round of direct talks organized by the U.S., after meetings earlier this year in Abu Dhabi that officials described as constructive but which also made no major headway. Expectations for significant progress in Geneva were low. Ukrainian President Volodymyr Zelenskyy accused Russia of "trying to drag out negotiations" while it presses on with its invasion.

Russia's top diplomat says that Moscow will observe the limits of the last nuclear arms pact with the United States that expired last week as long as it sees that Washington does the same. The New START treaty expired Feb. 5, leaving no restrictions on the two largest atomic arsenals for the first time in more than a half-century and fueling fears of an unconstrained nuclear arms race. Russian Foreign Minister Sergey Lavrov said Wednesday that even though the U.S. hasn't responded to President Vladimir Putin's offer to maintain New START's caps for another year, Moscow will respect the treaty's limits if the U.S. observes them too.

The Kremlin says it regrets the expiration of the last remaining nuclear arms pact between Russia and the United States, while President Donald Trump declared he was against keeping its limits and wants a better deal. The end of the New START treaty left no caps on the two largest atomic arsenals for the first time in more than half a century, fueling fears of a new nuclear arms race. Russian President Vladimir Putin expressed readiness Thursday to stick to the pact's limits for another year if Washington agreed. But Trump said he wants a new pact. The treaty was signed in 2010. It was extended in 2021 for five more years.

Envoys from Moscow and Kyiv have met in Abu Dhabi for U.S.-brokered talks to end the nearly four-year war. The discussions on Wednesday came as Russian cluster munitions killed seven people at a market in Ukraine. The talks include U.S. officials and aim to address key issues. But previous negotiations last month yielded no breakthroughs. The meeting also coincides with the expiry of the last nuclear arms pact between Russia and the United States. Moscow has continued to target Ukraine's energy infrastructure that has caused widespread damage. Ukrainian officials have expressed outrage. And repair crews are working to restore power amid freezing temperatures.

Ukrainian President Volodymyr Zelenskyy says Russia breached its commitment to hold off on energy infrastructure attacks for a week when it launched a major assault on Ukraine overnight. The strikes reported Tuesday came as NATO Secretary-General Mark Rutte visited Kyiv and a day before U.S.-brokered talks between Russia and Ukraine in Abu Dhabi, United Arab Emirates. Zelenskyy said Russia targeted the power grid in five regions of Ukraine in what he said was a bid to deny civilians light, heating and water during a harsh winter. He urged allies to send more air defense supplies and increase pressure on Russia. Talks between Moscow and Kyiv have been described as constructive, but a comprehensive settlement remains distant.
